I can't say much about these patches as a whole as they are rather big and I'm not aware of all the details of ZFS. However, one bit that makes the current implementation x86-specific is zfs_dev_init(). If you could move it to the MD part in the course of these patches that would be great. If you could also take the second patch in PR 165025 into account, which I plan to commit once the issue with the current ofw_disk.c are properly solved, that would be great.
